SPEUIFIGATION forming part of Letters Patent No. 672,635, dated April 23, 1901..

Application filed February 20, 1901. serial No. 48,117. (No model.)

To aZZ whom it may concern:

Be it known that I, HOWARD D. COLMAN, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Knot-Tying Implements, of which the following is a specification.

The object of this invention is the production of a hand-mounted power-driven knottying implement.

In the embodiment herein shown of'this invention the tying mechanism is intended to be worn constantly on the left hand of the operator and its parts to be operated by power extraneous to the hand upon which it is mounted. A thumb-lever is adapted to operate a friction-clutch for engaging the knotter mechanism with the driving means and for disengaging it therefrom. After the knotter mechanism has been driven through the cycle of its movement a coil torsion-spring returns said mechanism to its normal or starting position. a

The implement illustrated is adapted to tie spoolers knots; and it comprises a rotatable tying-bill having a shearing and clamping jaw and a movable stripper for grasping the thread, drawing the knot tight, and pulling it from the tying-bill.

In the accompanying drawings, Figure 1 is a side elevation of a knot-tying implement embodying the features of my invention, showing the mechanism in the normal or starting position. Fig. 2 is a side elevation of said mechanism viewed from the side opposite from that shown in Fig. 1, the parts of the mechanism being in a normal position. Fig. 3 is a rear end elevation of this knottying implement with its parts in a normal position. Fig. 4 is a top plan view of the mechanism, showing the knotter-bill after it has made one-fourth of a revolution from the normal position and with theother parts of the mechanism in the positions relative thereto. Fig. 5 is a view similar to the preceding one, showing the knotter-bill after it has made three-fourths of a revolution from the normal position, the threads being represented as wound about'said bill and the shearing and clam ping jaw of the bill open to receive the threads. Fig. 6 is a view similar to those of the two preceding figures, the knotter-bill being represented as having made one and one-fourth revolutions from its normal position, the threads having been cut off and clamped by the shearing and clamping jaw, and the knot being pulled from the knotterbill by the thread-holding arm. Fig. 7 is a view of the stripper mechanism, showing it detached from the body of the implement. Fig. 8 is transverse section through the threadholding arms E and F, showing the springlatch F and the surrounding parts in detail. Fig. 9 is a front end view of the cylinder which operates the shearing and clamping jaw. Figs. 10 and 11 are sectional detail views of the rotatable tying-bill and the cam-cylinder which operates the shearing and clamping jaw of said bill. Fig. 12 is a detail view showing in elevation the tying-bill and its cam-cylinder, it being represented in the position corresponding to that of Fig. 6, the threads being knotted over said tying-bill, the loose ends severed, and the knot about to be pulled from the bill by the stripper mechanism. Fig. 13 is an enlarged perspective view showing in detail the tying-bill. Fig. 14 is an enlarged view showing the position of the threads constituting the knot as the same is illustrated in Fig. 6. Fig. 15 is a view of a spoolers knot as formed by this mechanism.

Like letters of reference indicate corresponding parts throughout the several views.

In the construction of this implement I provide a standard A, having the integral overhanging arms A at its upper end and the transverse sleeve A at its lower end. A clip A surrounds said sleeve A and is adapted to have frictional engagement with the outer surface of the transverse sleeve by means of the clamping-screw A The clip A has a downwardly-extending stem A intended to lie within a suitable opening in the handle A and to be held rigidly in position therein by the set-screw A The handle A is provided with a handle-strap A in loop form for surrounding the hand of the operator, and this loopis made adjustable in sizein order to fitthe hand of any person. I have shown a buckle for providing this adjustment, but any suitable means may be employed for this purpose. It will be noticed that the stem A shear edge.

threads in the tying-bill. is fixed on the rear end of said kn'o'tter-shaft, being adapted to receive power todrive the may be turned with relation to the handle A and the sleeve A in the clip A in order to secure an adjustment of the implement to accommodate it to hands of different forms.

A shaft B is free to oscillate within the sleeve A collar B, fixed thereon, and between said collar and the clip A a coil torsion-spring B is situated, said spring being mounted on the shaft B and its ends secured to the collar B and the clip A The tendency of said torsion-spring is to oscillate the shaft B a certain distance in one direction, its purpose be ing to restore the knot-tying mechanism to its normal position after the driving power has operated it against the action of said spring. At the opposite end the shaft B carries the sector cam-gear B pinned to said shaft. The cam-groove B of the sectorcamgear is cut in the peripheral face-of the sector, and thet-eethof the gear are of skewgear form. The cam-groove B is of an outline somewhat resembling that of the letter U, with its arms widespread and curved outward at their upper ends.

0 is a knotter-shaft'rotatably mounted in bearings formed in the overhanging arms A of the standard A and carries the pinion O, the teeth of which are skewed to correspond with'those of the sector cam-gear B 1 The pinion C is affixed to the shaft in any suitable manner. I have shown it as frictionally engaging said shaft, but it may be positively secured thereto in any desired way.

This pinion O" is provided with a long "hub 'to occupy wholly the space upon the shaft 0 "between the supporting-arms A, and thus I prevent end movement of said shaft.

' cam-cylinder O ,which latter is rigidlymounted on the'standard A. This cam-cylinder is set eccentric to the knotter-sha'ftQ and its inner form is 'slightlyelliptical in order to produce the proper movement of the sheari'ng and clamping jaw 0 the Wingof said jaw engaging said internal cam. The flattened side of the tying-bill C is provided with a shear edge within the slot (l gand the jaw'C pivoted in said slot 0 with a'correspondin'g The opposite edge of said jaw is rounded slightly, so that the latter will clamp while'the oppositeed'ge severs the ends of the A friction-disk O mechanism.

T have now'described the mechanism for At one end this shaft carries the forming the knot and cutting the thread. I will next describe the stripper mechanism.

A supporting-plate D is secured to the top.

of the standard A and is provided with the fixed forwardly-extending guide-arm D for the thread. Rearward of the guide-arm D is the vertical bearing-sleeve D and near the opposite edge of the supporting-plate D is an upwardly-extending releasingstud D for a purpose to be mentioned later herein. Astopstud D at the forward edge of the supporting-plate limits the forward movement of the stripper mechanism. An oscillatory shaft E is adapted to lie within the vertical bearingsleeve D and this shaft carries the two crankarms E and E fixed to'said shaft. The former at the lower end of the shaft be'ars'the 'a-ntifrictiomroller E adapted to lie within the cam-groove B of the sector'c'am-gear B and the latter-at its outer end supports the pivotal arm E havingthe upwardly-extend- F is a thread-holding arm loosely mounted by means of its integral ears F on the 'osci'llatorys'ha-ft E and havingits outer'p'ortion l5 bent at an angle with the "plane of the body portion thereof. Theforwardend of the outer portion F of saidthread holdingarmis formed into a rearwardly-extendin g guide-arm F for the thread, between which arm and the fingers E the thread is clamped during the last part of the knot-tying operation, when the knotis being'dra'wn tight and stripped from the tying-bill. The fingers E embrace the said outer portion F 'of the thread-holding arm F, one finger lying on each side thereof. Asprin g F ,-coiled about the oscillatoryshaft E, is attached atits ends 'to'the arm E and IIO the thread-'holdin g arm Fahd by its elasticity of the cam-groove B forms a stop for the rearward movement of'the'arm E A springlatch F is pivotally mounted by the stud F on the thread-holding arm F and is adapted to engage the stud E onthe arm E and there- 'by hold the thread-holding arm F and the arm- E togethe'r, a spring coiled about the pivotal stud F tending to hold said latch in engagemen'tWith the stud. The latch F has an integralarm F extendingsubstantially at right angles 'thereto,andapin F fixed insaid arm F ,extends*d0wnward through aslightly-elo ngated opening F in the thread-holding arm F into apos'ition to be engagedby the upwardlyextehding releasing-stud D which stud by delaying said pin rocks the latch F on its'pivot and withdraws it from its engagement with the stud E.

ii the end of the elongated opening F and furguide-arm F is formed a little thicker than the thread-holding arm F, so that while the fingers E slide freely on the body of said arm they will tightly engage the guide-arm in order there to firmly grasp the thread.

The driving mechanism is supported upon a bracket G, fixed to the side of the standard A and extending rearward thereof. This bracket is provided with a transverse sleeve G near its lower end. A rock-shaft G is mounted in said sleeve, one end of which rock-shaft bears the thumb-lever G fixed to said shaft and extending forwardly therefrom to a point Where its forward end is easily accessible to the thumb of the hand upon which the implement is mounted. The opposite end of the rock-shaft Gr carries an upwardly-extending clutch-operating arm G also fixed to said shaft G. A longitudinallymovable shaft G is mounted in the bearing G integral with said bracket G, and at its forward end is provided with the rotatable friction-disk G fixed to said shaft, the clutchoperating arm G engaging the rear side of the hub of said friction-disk G This friction-disk has the usual leather face and coincides with the friction-disk 0 mounted on shown) running over said sheave G furnishes power to drive said sheave and the flexible shaft;

In the operation of the implement the left hand of the operator is slipped within the handle-strap A the loop being adjusted to the size of the operators hand, and the thumb of the operator placed upon the thumb-lever G Power is applied to rotate the flexible shaft G and the ends of the thread to be united, lying side by side, are drawn with the right hand of the operator over the outer end F of the thread-holding arm F and the guide-arm D, and said arm and said guide being inclined downward cause the two threads to slide into the forward ends of the thread-holding arm and the guide-arm, pass- The pin F when so rocked is at ing intermediately across the knotter-shaft 0 directly under the point of the ,tying-bill C A downward pressure of the thumb upon the lever G moves the rotating friction-disk G into contact with the corresponding friction-disk G fixed to the knotter-shaft G. The knotter-shaft is rotated by the power thus applied and the sector cam-gear driven by reason of the skew-gear connection between said shaft and said sector-carn. The first quarter of a revolution of the tying-bill 0 turns it into the position indicated in Fig. 4, the point of the tying-bill lying over the threads. During this quarter-revolution of the knotter-shaft the sector cam-gear B was moved, causing the roller E on the arm E to travel outward a little distance in the cam-groove B oscillating the shaft E and moving forward the arm E and the pivotal arm E with its clamping-fingers E said fingers sliding forward, one on each side of the outer portion F of the thread-holding arm F, also shown in Fig. 4 of the drawings. Continued oscillation of the cam continues the forward movement of the clamping-fingers E until, as the roller E reaches the lowest point in the cam-groove B, the fingers E coincide with and embrace the outer end of the threadholding arm F, clamping the thread between the fingers and the guide-arm F During the same time the stud E was moved into engagement with the spring-latch F locking the arm E and the thread-holding a'rm F together, as shown by Fig. 5 of the drawings. At this point the tying-bill has been rotated through three-quarters of a revolution, and by reason of the interior conformation of the cam-cylinder 0 its shearing and clamping jaw C is open readyto receive the thread during the next quarter-revolution of said knotter -shaft. The continued rotation of the knotter-shaft throws the uptending or "return side of the cam-groove B into contact with the roller E and as the tying-bill is turned into the position indicated in Fig. 6 the thread-holding arm F and the arm E are thrown backward and outward, stripping the knot from the end of the tying-bill, the camsurface within the cam-cylinder 0 having previously closed the shearing and clamping jaw to cut off the threads and to hold the short ends thus formed while the knot is being stripped off the tying-bill by the backward movement of the clamping-fingers F. in conjunction with the thread-holding arm F. When the tying-bill reaches the position indicated in Fig. 6, the ends of the thread will be pulled from the bill, and the pin F having now engaged the releasing-stud D further rearward movement of the arm E causes the latch F to be disengaged from the stud E and the fingers It to be withdrawn from the guide-arm F whereupon the spring F throws the thread-holding arm into its forward position against the stop-pin D The thread is now free to be withdrawn, and the thumblever G is released, permitting the G should he moderately rapid.

lever Gr is'depressed for an instant only, this being sufficient to permit the full operation friction-disk G to be withdrawn from con tact with the friction-disk C The power stored in the coil torsion-spring B by the op- Q erative movement of the mechanism now ref stores said mechanism to its normal position, and during said restoring movement the mechanism is operated as just described, ex- '5 cept that the knotter-bill is rotated in the opposite direction.

The arm E and the thread-f holding arm F will be engaged and moved backward together until the pin F encounters the releasing-stud D when the latch F will, release the stud E and the thread-holding arm F will be thrown into its forward or nor- 2 mal position by the spring F The rotation of the flexible shaft G and the friction-disk The thumbof the tying-mechanism. As soon as the pres-;

sure upon said lever is released the mechanism automatically assumes its normal position, ready to be operated again. I claim as my invention- 1. In a knot-tying implement, in *combination, a (knot-forming mechanism; means for securing said mechanism to the hand of the anism to' form a knot.
